Close next-stable branch for merge to stable.
Merge next-stable to stable.
Added tag release_2013.08.12 for changeset 1ae95b3aa98d
Add some overly simple baseline unit tests for visualizations plugin behavior.
Planning on refactoring out self.plugin_directory, is this simplified logic sufficient or was it the way it was for a good reason?
Refactor plugin framework to allow multiple plugin directories (like tools framework allows multiple tool roots).
Idea here is to allow some plugins to be managed by Galaxy team inside root and some plugins to be managed outside of Galaxy root by deployers, etc.... This will help keep merges unnecessary or as minimal as possible and should ease efforts like Debian packaging of Galaxy.

The need to actually modify the Galaxy code base is an unfortunate aspect of the way dynamic job destinations and dynamic toolbox filters have been implemented. Bringing these under a generic plugin framework and allowing them to be tweaked outside of the Galaxy code base would be wins.
Add some test cases for plugins configured from multiple directories.
